| Abstract: | Difficultly combustible high boron-containing organic compounds are quantitatively burnt by adding anhydrous Na3SO3 or Na3SO4 as additive to form Na2B4O7 which is absorbed by dilute acid and transformed into H3BO3. By the present procedure, the formation of B4C can be avoided. This method is suitable for decomposition of many non-volatile B-containing organic compounds. |
